We really need a list of AM holders which can be checked by ourself
I disagree. Some shareholders don't want their holdings publicized / you could just look at where the div payments are going to / see which addresses hold shares - it's all public.
I mean which only record the address and amount.
And, it's different from the public info on blockchain. It's the info from AM side, which might be wrong.
Huh? The info from the AM side
is the list of shareholders. It's not wrong, if you're not in the list that's used to pay dividends then you don't own any shares and no amount of pleading or begging to anyone will change that.
